NixOS Package Management & Dotfiles
User input: $ARGUMENTS
Style
Comment sparingly in .nix files. Nix is declarative so code is self-documenting. Only add comments to:
- Delineate sections in long package lists
- Explain non-obvious workarounds
- Note dependencies between options that aren't apparent
Instructions
-
Read context: ~/Dotfiles/CLAUDE.md for layout
-
Parse request:
- Install/remove package: Edit
hosts/fw13/default.nix
- Search:
nix search nixpkgs <query>
- Update:
nix flake update then rebuild
- Config changes: Edit appropriate module in
modules/
- Claude settings: Edit
~/Dotfiles/sources/claude/ (see below)
-
For packages:
- Confirm package name:
nix search nixpkgs <name>
- Edit
hosts/fw13/default.nix under home.packages
-
Apply: Run nrs
- If rebuild fails, analyze error, fix, retry
- Report success
-
Commit (after successful rebuild):
git add -A && git commit -m "..."- Ask before push
Package Locations
- User packages:
hosts/fw13/default.nix → home.packages
- Flake inputs:
flake.nix
- System services:
modules/nixos/services.nix
Claude Code Settings
All Claude Code configuration is managed via Home Manager. Never edit ~/.claude/ directly - those files will be overwritten on rebuild.
Source of truth:
~/Dotfiles/sources/claude/
├── CLAUDE.md # Global context
├── settings.json # Claude Code settings
├── commands/ # Slash commands
├── skills/ # Skills like this one
└── context/ # Shared context files
Workflow for Claude settings changes:
- Edit the source file in
~/Dotfiles/sources/claude/
- Run
nrs to deploy
Examples:
- Modify settings: Edit
~/Dotfiles/sources/claude/settings.json
- Add command: Create
~/Dotfiles/sources/claude/commands/my-command.md
- Add skill: Create
~/Dotfiles/sources/claude/skills/skill-name/SKILL.md
